Definitions
- the invention relates to a device for displaying a movement of a Patients according to the preamble of claim 1.
- EP-A-530 596 is a device for measuring the electromagnetic Radiation of a patient's head at which the patient is known a couch is stored in a housing into which a light guide is guided, which is attached to the head end of the table.
- the light guide is made by one light emitting diode pulsed with light that hits the head of the Patient is directed.
- a retro reflector element is attached to the head.
- a another light guide receives the light and received from the retro reflector element directs it to a photocell.
- a limit detector detects if this is on the photocell incident light falls below a lower limit.
- the invention has for its object to provide a device with which Movement of a patient's body and part of the body with simple means can be automatically monitored when the body or body part is undergoing therapy or subjected to a diagnosis.
- the device according to the invention contains a laser source in the form of a modulated one Semiconductor laser, the beam of which is linear. Furthermore, an optoelectronic Receiving device is provided, which receives the reflected laser beam and a appropriate signal generated. The laser beam is reflected by an am Retro-reflective element that can be attached to the patient. With the receiving device also a display and / or alarm device connected to generate a Indicator or alarm signal when the reflected beam fails to appear.
- the reflected beam is also sharply limited, so that even slight deflections of the reflector element from one Standard direction can be detected by a suitable optical receiving device can.
- the invention assumes that it is relatively simple to use a retro reflector element to be attached to a part of the patient's body. Because of the low Transverse expansion of a laser beam only needs to cover a small area and can therefore also be arranged within the area, for example one Is subject to radiation treatment or diagnosis.
- the reflector element can be equipped with suitable means for attachment to the patient become. It preferably has a layer of pressure-sensitive adhesive on its rear side
- the reflector element is preferably a disposable item, which after use is not used again. However, it is also easily conceivable to use a reusable one Provide reflector.
- the device according to the invention is connected used with a radiation or diagnostic device, it can make sense be to integrate them into the radiation or diagnostic device. Laser and receiving device are housed in a common housing.
- the display and / or alarm device If the patient moves, the display and / or alarm device generates a corresponding optical and / or acoustic signal. Furthermore, also an electrical signal can be generated, for example for an interruption of the Radiation treatment or diagnosis.
- the single figure shows an apparatus according to the invention in an extremely schematic manner.
- a laser light source 12 is arranged in a housing 10 and has a linear shape Beam, as indicated at 16, generated.
- an optoelectronic Receiving device 14 arranged the reflected laser beam receives, which is thrown back by a relatively small retro reflector element 18 becomes.
- the reflector element is made using suitable means (not shown here) attached to the patient, here for example on the forehead of a patient's head 20, for example with the help of a Hafl glue.
- the head is, for example, a radiation treatment subject.
- the preferably fixed laser 12 generates on Head 20 the line 16.
- the reflector element 18 is in the area the line 16 applied, and the receiving device 14 monitors whether the reflector element line 16 leaves.
- the device 10 can be arranged at any location be and is using a power cord 28 with energy provided. It can therefore easily be arranged on or in any radiation and X-ray apparatus these are integrated.
- the size of the reflector element 18 determines the sensitivity the device. The smaller it is, the more The motion monitor reacts more sensitively.
